Soften the tones into each other with the brush

The check is re-painted, giving more rose-color to the local tone by using madder lake, vermilion, white, yellow ochre, and a little ivory black.

Add the high light on the cheek bone if there is one, and the light is always lighter just there, even if the gradation is so soft as not to show much.

Soften the tones into each other with the brush, but without any other attempt at blending than this gives. Do not pass the brush over the whole surface, but unite the edges only, keeping distinct the shape of each different tone as nearly as possible while thus modeling them into one harmonious whole.
